Whilst fucking a girl from behind, you pull out, come on her back. When she turns around you pull out your trusty can of mace, spray her directly in the eyes. She will then grap her cheeks and scream "AHHHHHHH" similar to Macauly Culkin in his premier roll as Kevin McAllister in the movie 'Home Alone'

I was fucking this lady cop from behind, came all over her ass and then grabbed that bitches mace and gave her the Home Alone
